I can't remember the name or the auther but the story was about a uke who was in love with two sempai so they double team him in maybe a gym storage shed and he admits he loves them both and they have a threesome including a scene with one of them blowing him and the other rimming him. thanks for taking the time to read this.

It should be the first chapter form Bachi Bachi (KIJIMA Hyougo)
Also the fourth chapter - Sasayaka na Yokubou, from Three and a half is quite similar. (minus the threesome)

And next time, please make sure to post yaoi/yuri related stuff in the appropriate section 🙂

Thanks but those aren't what I am looking for. Still they are good so thank you. The one I read before the sempai were the mean ones and the uke was tied up but also into it. I'll try to remember more.

More things it's not but are similar to list because that might help find it... and in looking amybe i will remember more

Bokura no Mitsudomoe Sensou
Docchi ni Suru?
Iberiko Buta
Hot Triangle but I think the art style was similar to this one
I remember the two seme do rock paper scissors to see who will go first...

This time hopefully it won't be wrong 🙂
Chapter 6 - Yokubari wa Dame na no from Nurse ga Oshigoto.

yes thank you omg you are a genius
